Description
Summary:Arising from: C. M. O'Reilly, S. R. Alin, P. -D. Plisnier, A. S. Cohen & B. A. McKee Nature 424, 766-768 (2003); O'Reilly et al. replyIn their analysis of Lake Tanganyika's ecosystem, O'Reilly et al. claim that climate change, in the form of rising temperatures and falling winds, is causing a decline in the lake's productivity. However, their own data show that air temperatures were either steady or dropped slightly between 1952 and 1978, rising only slightly between 1980 and 1992, and that wind speeds have increased by 35% since 1985. These climate changes therefore have no correlation with either lake temperature or productivity, so it cannot be inferred from their data that climate change is the cause of the productivity decline.
